commit efe00579c04e02b6132c678962ce8050c8759bee
Author: Pan Li <pan2...@intel.com>
Date: Wed May 29 14:15:45 2024 +0800
RISC-V: Add testcases for scalar unsigned SAT_ADD form 1
After the middle-end support the form 1 of unsigned SAT_ADD and
the RISC-V backend implement the scalar .SAT_ADD, add more test
case to cover the form 1 of unsigned .SAT_ADD.
Form 1:
#define SAT_ADD_U_1(T) \
T sat_add_u_1_##T(T x, T y) \
{ \
return (T)(x + y) >= x ? (x + y) : -1; \
}
Passed the riscv fully regression tests.
gcc/testsuite/ChangeLog:
* gcc.target/riscv/sat_arith.h: Add helper macro for form 1.
* gcc.target/riscv/sat_u_add-5.c: New test.
* gcc.target/riscv/sat_u_add-6.c: New test.
* gcc.target/riscv/sat_u_add-7.c: New test.
* gcc.target/riscv/sat_u_add-8.c: New test.
* gcc.target/riscv/sat_u_add-run-5.c: New test.
* gcc.target/riscv/sat_u_add-run-6.c: New test.
* gcc.target/riscv/sat_u_add-run-7.c: New test.
* gcc.target/riscv/sat_u_add-run-8.c: New test.
